health assessment practice questions

Correct Answer: C

Rationale: The correct answer is C because pain in the ear when people speak loudly can be a sign of a middle ear infection. This is due to increased pressure in the middle ear caused by inflammation or fluid buildup. Recruitment (B) is a phenomenon related to hearing loss, not ear pain. Cerumen impaction (D) would not typically cause pain in response to loud sounds. It is not normal for a person of that age to experience ear pain when people speak loudly (A).

Correct Answer: C

Rationale: Step-by-step rationale: 1. Anisocoria is a condition where pupils are of unequal size. 2. It is typically caused by issues in the eye muscles or nerves controlling pupil size. 3. The nurse would expect to observe pupils of different sizes. 4. Dilated pupils (choice A) and excessive tearing (choice B) are not indicative of anisocoria. 5. An uneven curvature of the lens (choice D) does not directly relate to pupil size differences. Summary: Correct answer C is supported by the definition of anisocoria and its usual presentation. Choices A, B, and D are incorrect as they do not align with the characteristic feature of anisocoria.

Correct Answer: C

Rationale: The correct answer is C because the frontal sinuses are indeed fairly well developed at birth. This is true as the frontal sinuses start developing around the age of 7-8 years but are present in a rudimentary form at birth. This is because the frontal bone grows rapidly in the first few years of life, allowing for the development of the frontal sinuses. Choice A is incorrect because the sphenoid sinuses are not at full size at birth; they continue to develop throughout childhood. Choice B is incorrect as the maxillary sinuses reach full size around the teenage years, not after puberty. Choice D is incorrect as the frontal sinuses are also present at birth, along with the maxillary and ethmoid sinuses.

Correct Answer: B

Rationale: The correct answer is B: the lump is mobile and not hard. A cancerous thyroid nodule is typically fixed and hard, whereas a noncancerous nodule is more likely to be mobile and soft. This characteristic suggests it may be a benign condition such as a thyroid cyst rather than a malignant tumor. The other choices are incorrect because A: tenderness does not necessarily indicate benignity or malignancy, C: disappearance when smiling is more related to a salivary gland issue, and D: hardness and fixation are more indicative of a potentially cancerous nodule.

Correct Answer: D

Rationale: The correct answer is D: It helps equalize air pressure on both sides of the tympanic membrane. The eustachian tube connects the middle ear to the nasopharynx, allowing for pressure equalization. During activities like swallowing or yawning, the tube opens to allow air to flow in or out, maintaining equal pressure. This function is crucial for proper hearing and preventing discomfort or damage to the tympanic membrane. Choice A is incorrect as cerumen is produced by ceruminous glands in the ear canal, not the eustachian tube. Choice B is incorrect as the eustachian tube normally remains closed and opens only intermittently during specific actions. Choice C is incorrect as the eustachian tube does not connect the middle and outer ear; it connects the middle ear to the nasopharynx.
